Kawasaki Syndrome-Like Illness Associated with Infection Caused by Enterotoxin B-Secreting Staphylococcus aureus

Abstract

Two children had symptoms and clinical signs that were characteristic of the diagnostic criteria for Kawasaki syndrome, temporally associated with Staphylococcus aureus bacteremia. One child initially had focal osteomyelitis that was evident clinically and radiographically, and radiographic evidence of multifocal osteomyelitis was noted at follow-up. The blood-borne S. aureus isolates from these two patients secreted staphylococcal enterotoxin B and were negative for toxic shock syndrome toxin. Staphylococcal and streptococcal superantigens may play a role in the pathogenesis of some cases of Kawasaki syndrome or Kawasaki syndrome-like illness.
